Application July 9, 1949, Serial No. 103,870

1 Claim. 1

This invention relates to improvements in a rubber heel having aremovable heel plate.

The object of the invention is to provide a fastening means forremovably retaining a heel plate on a soft rubber heel. The plate hascountersunk holes for receiving screws forming the fastening means.

The object is obtained in the manner described in the followingspecification and drawings in which:

Figure 1 is a top plan view of a wire retaining member engaging asecuring screw;

Figure 2 is a top view of the soft rubber heel showing the position ofthe cavities;

Figure 3 is a plan view showing the heel plate held in position by thescrews;

Figure 4 is a section taken on the line 4-4 of Figure 2;

Figure 5 is a section taken on the line 5-5 of Figure 3 showing a screwin position;

Figure 6 is a view similar to Figure 5, showing a modification.

In Figure 1, l0 are the legs of a U-shaped wire retaining member II. Thespace l2 between the legs ID is of sufi'icient size to receive the tipof screw l3. The legs will engage the threads on the screw and be spreadby the screw as it is rotated, thus locking the screw in place.

In Figure 2, the position of the heel plate 15 is shown in dotted lines,and 14 indicates rectangularly shaped cavities in the top surface of thesoft rubber heel [1.

In Figure 3, the heel plate is shown screwed to the bottom surface ofthe rubber heel.

In Figure 4., I6 is a screw guiding hole in the bottom of the heel, andI4 is one of the aforementioned rectangular cavities in the top of theheel.

In operation the wire retaining members I l are inserted in cavities l4under compression, so that upon release their natural spring will retainthem in place. Next the plate is positioned on the bottom of the heeland the screws are inserted through countersunk holes in the plate, intoholes I6 in the heel. The screws are then screwed into the heel cavitiesl4, thus passing between the legs of the wire retaining member II, whichmember acts as a look. It is to be noted that the screws are of lesslength than the thickness of the rubber heel, so as not to impair thecushioning effect of the soft rubber heel.

In the modification shown in Figure 6 the cavities M are omitted and thewire retaining members I l are embedded in the soft rubber heel.

I claim:

A rubber heel having holes formed in its wear face adapted to havescrews inserted therein, and cavities formed in its upper face, thewalls of each cavity retaining a U-shaped wire member in fixed position,the two legs of the said wire member being adapted to engage the threadson opposite sides of a tapered screw member for retaining a heel plateon the rubber heel, said holes being aligned with the space between thetwo legs of said wire member.
